An incorrect #ifdef caused a pair of harmless warnings when CONFIG_PM_SLEEP
is disabled:
drivers/usb/dwc3/dwc3-of-simple.c:223:12: error: 'dwc3_of_simple_resume' defined but not used [-Werror=unused-function]
static int dwc3_of_simple_resume(struct device *dev)
^~~~~~~~~~~~~~~~~~~~~
drivers/usb/dwc3/dwc3-of-simple.c:213:12: error: 'dwc3_of_simple_suspend' defined but not used [-Werror=unused-function]
static int dwc3_of_simple_suspend(struct device *dev)
Since the #ifdef method is generally hard to get right, use
a simpler __maybe_unused annotation here to let the compiler
drop the unused functions silently. This also improves
compile-time coverage.
